Littelfuse Z32F12811ATS

Description

Zilog’s Z32F1281 MCU, a member of the ZNEO32! Family of microcontrollers is a cost-effective and highperformance 32-bit microcontroller. The Z32F1281 MCU provides 3-phase PWM generator units which are suitable for inverter bridges, including motor drive systems. The two built-in channels of these generators control two inverter motors simultaneously. Three 12-bit high speed ADC units with 16-channel analog multiplexed inputs are included to gather information from the motor. The Z32F1281 MCU can control up to two inverter motors or one inverter motor and the Power Factor Correction (PFC) function simultaneously. Four on-chip operational AMPs and four analog comparators are available to measure analog input signals. The operational amplifier can amplify the input signal to the proper signal range and transfer it to the ADC input channel. The comparator monitors external signals and helps create an internal emergency signal. Multiple powerful external serial interface engines communicate with on-board sensors.
